Need quick help with diff files in current directory!!!

i have a problem that needs to be solved with CSH , SED or AWK as soon as possible.

I need to write a program which creates a directory called backup (if it does not exist). The program then compares all the ordinary files in the current directory and if two files are identical, it moves one of them to the backup directory. The program should finally display the names of the files moved or the message: “No duplicate files found” if no two files are identical.

i have been trying out with the diff and cmp command. but i am not able to write a script to compare all the files in the current directory. can anyone help me out here?

NAME
zcmp, zdiff - compare compressed files SYNOPSIS
zcmp [ cmp_options ] file1 [ file2 ] zdiff [ diff_options ] file1 [ file2 ] DESCRIPTION
Zcmp and zdiff are used to invoke the cmp or the diff program on files compressed via gzip. All options specified are passed directly to cmp or diff. If only file1 is specified, it is compared to the uncompressed contents of file1.gz. If two files are specified, their con- tents (uncompressed if necessary) are fed to cmp or diff. The input files are not modified. The exit status from cmp or diff is pre- served. SEE ALSO
cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1) BUGS
Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified. ZDIFF(1)
